SPECIFICATION forming part of Letters Patent No. 351,689, dated October26, 1886.

' Application filed May 6, 1886. Serial No. 201,351. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM HENRY Bos- WELL, a citizen of the UnitedStates, residing at Manson, inthe county of Calhoun and State of Iowa,have invented certain new and useful Improvements in Rabbet-Planes; andIdo declare the following to be a full, clear, and exact description ofthe invention, such as will enable'others skilled in the art to which itappertains to make and use the same,reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

, Figure I of the drawings is a representation of this invention, and isa top view. Fig. 2 is an end view. Fig. 3 is a detail, and is a verticalsection through one of the cast-metal plates.

My invention relates to rabbet-planes (lesigned for use in makingrabbets of any desired depth and width in the material to beworked,without previously having to gage the rabbet or use abevel-square; and the invention consistsin the construction and novelcombination of parts, as hereinafter described, and pointed out in theclaim.

Referring by letter to the accompanying drawings, A designates the stockof the plane, which is providedwith the bit-iron B, held in the stock bythe wedge C, and the stock may be with or without a handle, according tothe A kind of plane-stock used. At its ends the stock A of the plane isprovided with the -cast-metal platesD and E, which plates are providedwith longitudinal parallel slots F G, near their upper and lower edges,said slots extending nearlyfrom end to end of said plates, the

plates being beveled on their rear faces along,

the edges of the slots toform elongated countersinks, in which fit theheads H on the screwstems I.-

-J J are rectangular plates secured to the outer faces of the slottedplates. D E, said plates J J being held to their adjustments on theouter faces of the slotted plates D E by the screws I and thumb-nuts KK.

L L are pivoted plates, secured to the. rectangular sliding plates J Jby pivots M, passed through their lower inner corners. The pivotedplatesL L are provided with are slots N, in their cam-shape portions 0, andfrom these cam-shape portions 0 project integral arms P, between whichthe gage-bar Q is secured by screws R It, passed through holes in thearms P into the ends of the gage-bar Q.

By loosening the thumb-nuts K K the gagebar can be moved in or out asfar as the parallel slots will permit the slotted rectangular plates toslide.

By loosening the screws Y Y, passed through the arc slots N, thegage-bar Q may be turned on its pivots, and be thereby caused to assumethe required angle, after which the thumb-nuts V V may be tightened tohold the gage-bar at the angles to which it has been adjusted while theplane is being used. The upper edge of the gagebar is beveled to fit thebottom of the plane and hold the gage-bar at the proper angle when saidedge is moved under the stock of the plane.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s

The improved rabbetplane described, consisting of the stock A, theplates-D E, having ing the parallel longitudinal slots and secured tothe opposite ends of the stock in a plane relatively at right angles tothe face thereof, the sliding rectangular plates J,held in slidingengagement with the said end plates by the transverse screws and nuts IK, the gage-bar, the plates B,'having a semicircular slot, the thumb-nutworking therein, an arm, 1?, for attachment to the ends of the saidgage-bar, and their lower inner portions pivoted to a like point of thesliding end plates, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
